18 Claims.

My invention relates to apparatus by which glue, or other adhesive, maybe applied to workpieces, it being especially adapted for use'in con-.

nection with the gluing of heel-portions, as heelplate, the latter beingperforated. The pot, to-

bases or lifts, to prepare them for nailing to shoes. Herein it isdisclosed as an attachment for the heeling machine which is the subjectof an application for Letters Patent of the United States, filed in thenames of- John F. Standish and Lester S Macdonald on May 28, 1937 andbearing the Serial No. 145,320.

In gluing attachments for heelers, there is commonly provided a rollrotatable in a glue-receptacle and turned sumciently during eachoperating cycle of the associated machine to present a freshly coatedsurface to which the operator may apply the cup of the next heel to beattached. As the glue is lowered in the receptacle by its use, the rollbrings up varying quantities. When the receptacle is first filled, theapplication to the heels may be excessive, but, as the work proceeds andthe charge upon the roll diminishes,the heels may receive too littleglue. It is an object of this invention to present for application, in amanner convenient for the operator, substantially unvarying quantitiesof an adhesive regardless of its depth in the receptacle. This object Iattain by combining with the receptacle an adhesivesupplying member,which may consist of a plate, and an applying member, preferably a roll,the supplying member being arranged to lift the adhesive from that inthe receptacle, while the applying member moves toward and from thereceptacle to take it from the supplying member. By this arrangement, asthe members travel along each other, there may be produced a delivery tothe applying member, which, within working limits, is independent of thedepth of the adhesive in the receptacle and which is distributeduniformly upon said applying member. To avoid an unduly heavy coatingupon the applying member, the supplying member is preferably perforated,so, upon engagement between the two members, the excess of the adhesivemay escape under the pressure from the path of the applying member. Forthe gluing of the cups of heels, the applying member preferably has atransverse contour approximating that of the heel-cups and thecontacting surface of the supplying member is best 'complementallyformed. As herein disclosed, the apparatus has a glue-pot with which areassociated slides carrying the supplying membr and the applying memberand oppositelyreciprocated to establish contact between said members.This movement may be effected by reciprocating one of the slides andconnecting the other to it by racks and an intermediate pinion. Theapplying member is preferably in the form of a rotatable, convex rolland the supplying-member a concave gether with the plate and roll orother glue-supplying and -applying members, are shown as covered bysections hinged at opposite sides of the pot and meeting above it. Suchheel-attaching machines as that previously referred to have elementsoperating through definite cycles successively controlled by theoperator, and, to insure the correct presentation of the applying memberwith a fresh coat ofthe adhesive ready to receive contact of the heel tobe attached, I so reciprocate the members of the applying apparatus froman element of the machine, that their movement stops at the end of anoperating cycle with the applying member raised from its receptacle andthe supplying member lowered therein.

The accompanying drawings illustrate a particular embodiment of theinvention,

As fully set forth in the previously-mentioned application, a. heelingmachine, to which this applying apparatus maybe attached, has a frame l(Fig. l) carrying nailing mechanism l2 and an opposed heel-engaginPressure-head l4 movable toward and from the nailing mechanism in guidesl6. Successive loads of nails are transferred by a reciprocatoryloader-block ill to the nailing mechanism, for insertion in the work,from a foot-plate 20 through which they are delivered. The actuatingmechanism for the loader-block includes a spindle 22, oscillating in theframe under the control of a hand-lever 23 once during each operatingcycle of the machine.

It is usually desired to apply to each heel, before it is nailed, acoating of an adhesive over the cup. My improved applying apparatus forthis purpose is shown at A. Secured to one of the guides I6 is a bracketconsisting of a. depending bar 24 carrying at its lower extremity amounting plate 26. Pivoted at opposite sides of the lower portion of theplate to swing horizontally are bolts 28, 28,'arranged to enter slots inspaced lugs 30, 30 projecting from the bottom of a receptacle 32 forglue or other adhesive. This glue-pot has a cover preferably comprisingopposite sections 34, 84, each of which is pivoted upon a lug 38 at oneside of the top of the plate 26. The cover-sections meet at the centerto furnish a complete closure for the pot and rise considerably above itto give a space, the purpose of which will later appear. By looseningthumb-nuts upon the bolts 28, 28 and swinging aside said bolts, the potmay be removed readily for cleaning, leaving the cover undisturbed.Guided in spaced vertical ways 38, 38 in the plate 26 are slides 40,42'having their opposite ends bent inwardly and downwardly toward theinterior of the pot. Projecting horizontally from the down-turned end ofthe arm 40 is a spindle 44, which is normally situated above the pot.About the spindle is freely rotatable an applying roll 46, best of somesuch yieldable material as soft rubber, and with its convex peripheryapproximating in contour the transverse contour of the heel-cups whichare to be coated. By'having the form of the roll-surface a mean betweenthe extremes of the heel-cups, the yield of the roll will allow it toconform properly to the entire range of work. Fixed to the overhangingend of the slide 42 is a horizontal arm 48 projecting from a plate 50,which in the lower position of the slide preferably reaches from a pointsomewhat above the top of the pot nearly to the bottom thereof.Horizontally the plate is concave, its contour being substantiallycomplemental to that of the roll. Itis provided with numerousperforations 52, through which glue may pass, and at its upper extremity54 is flared out,- wardly to permit the reception of the roll by theconcavity without interference. The v adjacent edges of the slides 40and 42 carry rack-teeth 56 and these are connected by a pinion 58, theoutwardly projecting spindle of which is free to rotate in a plate 62attached to the bracket-plate 28 between the slides.

One of the slides, as that carrying the plate 50, is extended downwardlyat 64 below the plate 26. At its lower end, it is joined by a link 66 toa bellcrank-lever 68 fulcrumed upon the frame. The lever is connected bylink 10 to an arm I2 fast upon the end of the spindle 22 outside theframe. Normally, or when the heeling machine is at rest with theloader-block I 8 in its rearward position beneath the foot-plate 20, theroll 46 is raised to the extreme of its upward travel above the pot 32,and the plate 50 is correspondingly lowered, a considerable portionbeing immersed in the glue, which is indicated at G in Fig. 2. Theoperator depresses the lever 23, causing oscillation of the spindle 22.As a result of this, the loaderblock 18 containing a load of nailsadvances and delivers them to the nailing mechanism l2. By theconnection between the spindle and the depending portion 84 of the slide42, this raises said slide and through the pinion 58 simultaneouslylowers the slide 40. The roll 46 is thereby carried toward and into thepct 32 above the glue-level, while the plate 50 rises bringing up acoating of glue upon its concave face. This relation is indicated indotted lines in Fig. 2. In these opposite movements of the roll andplate, they travel relatively in contact with each other, transferringglue from the plate tothe entire periphery of the roll. Any excess ofthe adhesive, which with an imperforate plate might be pushed before theroll and gather in a ridge upon its surface, is permitted to escapethrough the perforations 52. The coating upon the roll will be smoothedupon it by the travel along the plate and when the nail-supplyingmechanism stops with the loaderblock again beneath the foot-plate, theroll will be again in the position illustrated in 1'18. 1 and carrying asubstantial uniform coating of the adhesive about its entire periphery.It is so located above the pot, that, with the cover-sections opened(Fig. 1), it will be convenient for the operator to draw the cup of theheel over it to receive a coating. By the simultaneous oppomtereciprocation of the applying and supplying elements, the extent ofmovement and the time required to deliver to the roll its coating ofadhesive are reduced, and, while the applying member is raised to givethe operator ready access to it, the

supplying member is lowered so a considerable portion is within theglue. This, together with thedistribution of the adhesive by the rollingof the applying member over the perforated plate, gives a substantiallyuniform coating in spite of lowering of the adhesive level during theuse of the apparatus. The heel thus coated is placed upon the heel-seatof a shoe at the nailing mechanism l2, the head I 4 lowered to applypressure to the work and the machine started for a single operatingcycle, during which the nails are driven into the heel. Thus, successivenail-delivering,

heel-cup-gluing and heel-nailing operations are performed. When theapparatus is not in use, the pct 32, together with the glue-applying and-supplying elements, may be completely enclosed by swinging up thecover-sections 34, 34. This reduces evaporation from and spoiling of theadhesive. The pot is removed for cleaning by simply releasing the bolts28, all the other elements of the apparatus remaining in place upon thebracket.
